A Hydrologist Studies The Effects Of Pollution On Marine Life? ›

Expert-Verified Answer

Both the hydrologist and oceanographer are concerned with water pollution and decontamination. The oceanographer will study all aspects of marine life, not just the water. Hydrologists, on the other hand, are concerned only with water and how availability of water and use of water impact the environment.

Hydrologists study how water moves across and through the Earth's crust. They study how rain, snow, and other forms of precipitation impact river flows or groundwater levels, and how surface water and groundwater evaporate back into the atmosphere or eventually reach the oceans.

As excess debris in the ocean slowly degrades over many years, it uses oxygen to do so, resulting in less oxygen in the ocean. Low levels of oxygen in the ocean lead to the death of ocean animals such as penguins, dolphins, whales and sharks. Excess nitrogen and phosphorus in seawater also cause oxygen depletion.

A toxicologist is a scientist who typically works with chemicals and other substances to determine if they are toxic, or harmful, to humans and other living organisms or the environment. There are different types of toxicology specialists.

Worldwide, hundreds of marine species have been negatively impacted by marine debris, which can harm or kill an animal when it is ingested or they become entangled, and can threaten the habitats they depend on. Marine debris can also interfere with navigation safety and potentially pose a threat to human health.

Data Collection and Analysis: Hydrologists are responsible for collecting and analyzing data related to water resources. This involves conducting fieldwork to measure water levels, flow rates, and quality parameters in rivers, lakes, groundwater systems, and other water bodies.

Hydrology is the study of the distribution and movement of water both on and below the Earth's surface, as well as the impact of human activity on water availability and conditions.

A hydrologist is a scientist who studies water and its movement around the planet. Hydrologists also study how water affects its surrounding environment and how environmental factors affect the quantity and quality of available water.

Hydrogeology is the study of groundwater – it is sometimes referred to as geohydrology or groundwater hydrology. Hydrogeology deals with how water gets into the ground (recharge), how it flows in the subsurface (through aquifers) and how groundwater interacts with the surrounding soil and rock (the geology).

What are the causes of marine pollution? ›

Most ocean pollution begins on land.

One of the biggest sources is called nonpoint source pollution, which occurs as a result of runoff. Nonpoint source pollution includes many small sources, like septic tanks, cars, trucks, and boats, plus larger sources, such as farms, ranches, and forest areas.

The Problem: Over 1 million marine animals (including mammals, fish, sharks, turtles, and birds) are killed each year due to plastic debris in the ocean (UNESCO Facts & Figures on Marine Pollution). Currently, it is estimated that there are 100 million tons of plastic in oceans around the world.

In the ocean, plastic debris injures and kills fish, seabirds and marine mammals. Marine plastic pollution has impacted at least 267 species worldwide, including 86% of all sea turtle species, 44% of all seabird species and 43% of all marine mammal species.

Environmental scientists and specialists analyze environmental problems and develop solutions to them. For example, many environmental scientists and specialists work to reclaim lands and waters that have been contaminated by pollution.

Environmental chemists monitor what is in the air, water, and soil to understand: How chemicals enter the environment; What affects those chemicals have; and. How human activity affects the environment.

Answer and Explanation: Ecologists are scientists who study living things in the environment. Ecologists study how organisms and their surroundings interact. The terrain, amount of vegetation, and the climate dictate what animals exist in the ecosystem.

Work Environment

Hydrologists spend time in the field (sometimes in remote or offshore areas) and in office settings.

Marine pollution is a combination of chemicals and trash, most of which comes from land sources and is washed or blown into the ocean. This pollution results in damage to the environment, to the health of all organisms, and to economic structures worldwide.

Nitrogen-based fertilizers which are routinely used in agricultural operations migrate to rivers and estuaries and ultimately to the sea where they promote harmful algal growth and deprive ocean areas of oxygen, creating multiple dead zones in which marine life cannot exist.

Solid Wastes

Plastic debris can be ingested or cause entanglement to marine life including marine mammals, seabirds, and sea turtles. Solid wastes generated by cruise ships include large volumes of food waste, cans, glass, wood, cardboard, paper, and plastic.
